How to Make Sea Grapes Pupusas

Salvadoran Masa Meets the Caviar of the Sea

Yes, this is real. Yes, it’s delicious. And yes—sea grapes pupusas are the oceanic, umami-packed, slightly briny, totally wild creation you didn’t know you needed.

Sea grapes, known in the culinary world as Caulerpa lentillifera, are a type of edible seaweed from Southeast Asia and coastal Central America. Also called green caviar, they pop in your mouth like nature’s boba and are full of oceanic goodness.

Today, we’re turning them into a one-of-a-kind pupusa filling. Salvadoran masa meets marine elegance. Let’s roll.

What Are Sea Grapes?

Sea grapes are:

• A type of green algae
• Naturally salty and crunchy with ocean flavor
• Packed with iodine, magnesium, and antioxidants
• Used in salads and sushi in the Philippines, Japan, and Okinawa

Now we’re folding them into cheese and masa, pan-searing them, and serving them Salvadoran-style. Because we can.

Ingredients

For the Masa:

• 2 cups masa harina
• 1 ½ to 2 cups warm water
• ½ tsp salt

For the Sea Grape Filling:

• ½ cup sea grapes (fresh, not dried)
• ¾ cup shredded cheese (quesillo, mozzarella, or cream cheese)
• 1 tsp lime juice
• Optional: ½ tsp sesame oil or olive oil
• Optional: chopped cilantro or scallions

Step 1: Prep the Sea Grapes

Rinse gently under cool water. Do not soak them too long—they’re delicate and can lose texture. Pat dry or shake off excess moisture.

💡 Note: These are best fresh. If using dried sea grapes, rehydrate in cool water for 5–10 minutes, then drain and proceed.

Mix with cheese and other filling ingredients. Taste—it should be briny, creamy, and a little zesty.

Step 2: Make the Masa

1. Combine masa harina and salt in a bowl.
2. Slowly add warm water, kneading to create a soft, non-sticky dough.
3. Cover with a damp towel while you work.

Step 3: Shape and Fill

1. Divide dough into 8–10 balls.
2. Flatten each into a palm-sized disc.
3. Add 1–2 tablespoons of sea grape filling.
4. Seal the dough around the filling and gently flatten into a thick disc.

Be gentle—sea grapes are delicate. Don’t mash them too hard.

Step 4: Cook with Love

Heat a non-stick skillet or comal over medium heat.

Cook each pupusa 3–4 minutes per side until golden with some browning.

Cheese will sizzle. Sea grapes will get warm but still pop.

Step 5: Serve with Style

These pupusas shine with:

• Curtido with lime and ginger
• A light drizzle of soy-lime salsa or ponzu
• Optional: sprinkle of toasted sesame seeds or crushed nori

Best served warm with a chilled coconut water or sparkling cucumber lemonade.

Final Thoughts: Coastal, Bold, and Totally Original

Sea grapes pupusas are not for everyone—they’re for the brave, the curious, and the flavor-forward.

So whether you’re beachside in La Libertad or just vibing in your kitchen with a bag of seaweed and a dream, remember:

The ocean is calling—and it wants to be inside a pupusa. 🫓🌊✨
